[3.5] conntrack executable not found on $PATH during cluster horizontal run
Last modified: 2017-07-24 10:11 EDT
Description of problem: While scaling a 300 node cluster up to 1000 projects and 4000 running pods, the following node Error level message popped a few times in the log on the master. I need to check other nodes to see if they hit it, too. Feb 7 22:56:58 192 atomic-openshift-node: E0207 22:56:58.045551 3115 proxier.go:755] conntrack return with error: Error looking for path of conntrack: exec: "conntrack": executable file not found in $PATH Feb 7 22:56:58 192 atomic-openshift-node: E0207 22:56:58.045600 3115 proxier.go:755] conntrack return with error: Error looking for path of conntrack: exec: "conntrack": executable file not found in $PATH Version-Release number of selected component (if applicable): 3.5.0.17 How reproducible: Unknown, saw a few instances during this test and will investigate other node logs Expected: No Error or Fatal messages.
This cluster was installed with the latest (as of 7 Feb) master branch of openshift-ansible/playbooks/byo/config.yml
We need to make sure that the libnetfilter_conntrack RPM is installed on any node running openshift-node.
/usr/sbin/conntrack is provided by conntrack-tools need to ensure that's installed on all nodes.
Including verifying availability on atomic host and/or the containerized node image. Currently libnetfilter_conntrack is required there but not conntrack-tools
change for the container version: https://github.com/openshift/origin/pull/12885 not containerized version: https://github.com/openshift/openshift-ansible/pull/3305
Verified this bug with openshift-ansible-3.5.13-1.git.0.562e91d.el7.noarch, and PASS. For rpm install,the following step is shown in node install. TASK [openshift_node : Install conntrack-tools package] ************************ After installation, check rpm package. # rpm -q conntrack-tools conntrack-tools-1.4.3-1.el7.x86_64 For containerized install: # docker run --rm -ti --entrypoint rpm openshift3/node:v3.5.0.32 -q conntrack-tools conntrack-tools-1.4.3-1.el7.x86_64
